press. it isonly' desirable to note the frame 1, the cyhnrler '2. and the recip'rocatory plate 3. The cylinder 2 has the usual peripheral shown, for holding the paper sheet- 2 in position under rotary movementof the cylinder 2 in the direction of the arrow marked thereon in Fig. 1. and which movement carries the said sheet against the type forms 5 that are carried by the plate 3.

The bo'xesll are yieldingly adapted to be movedinward a'nd heldor set by adjusting screws '14: appliedin the extreme outer end portions of said arms 8. Atits intermediate portion, the"shaft 12 is connected to the-bearing brackets transverse rod 16, The brackets 6 and ,7 con stitute an'choring devices, respectivelyflfoi' the a rms,8 and bearing frames 15. At one end the shaft 12 carries a spur pinion 17 is secured to andcarried bythe shaft 2% of the press cylinder 2. In F1g.' 4 said gear and pinion are shown with portlons of their practice they will, of course, be complete gears and pinions. The pinion 17 is preferably made adjustable, for an impor ant pm:-

"special matter on the'newspaper, both vermental clamping bars 26 are extended Cir-- i tal web 22 and at'their ends are provided tically and horizontally in respect to the '15 ordinary printed columns, segmental type .clamping bars 26 and channel-shaped type holding bars 27 are provided. The segcumferentially of the auxiliary printing cylinder, over the outer surface of the segmenwith hooks or detents 28 that hold the same in position. Set screws 29 are preferably applied to the keepers28 at one end of the bars 26 to rigidly secure said bars in any. desired lateral adjustment on the segmental web 22.- This web 22, it will be noted.

affords a bearing surface for the type Y that are held between the bars 26. channeled bars 27 are adaptedto hold type Y and at their ends they are notched at 30 to straddle the inner flanges 25*of the cylinder head 21 and are provided with set screws 31 engageable with said flanges to secure the bars 27 in any desired set adjustment circumferentially of the auxiliary printing cylinder.

The cylinder heads 21 are provided. with peripheral groovesthat partly receive small rubber tires'32 that run with frictional contact with the peripheral portion of the main cylinder 2. These tires 32 hold the auxiliary printing cylinder properly spaced from. the main cylinder or, in other words, hold the said auxiliary cylinder so that the faces of .the type Y and Y will be brought into I proper printing contact with the paper sheet- .2 carried downward by the main cylinder 2. It is, of course, evident that with this arrangement of the auxiliary printing device, the advertising or other matter set up by the type Y and Y will be printed on' the sheet before the sheet is subjected to the main body of type-5, and it will also be understood that this auxiliary printing device will print in space on the paper sheet corresponding to blank space left .in the main body of type 5. Attention is here called to the fact that by adjustment of the auxiliary printing cylinder circumferentially, the type Y and Y? may be set to print in the desired space'bn the paper sheet. This adjustment made possible by adjustment of the gear 17' in respect to the disk 19, which latter, it will be remembered, is

other The rigidly secured to the shaft 12. Also the printing point of the type Y and Y may be varied by movement of the type between the l bars 26 circumferentiallyof the cylinder, as well as transversely thereof.

To-supply ink automatically to the type Y and Y we provide an inking mechanism which is preferably constructed as follows: At each rotation of the auxiliary printing cylinder, the said type are moved against the under surface of an ink delivery roller 33', the shaft of which is mounted in bearing boxes 34 adjustably seated in bifurcated projections 35 of the bearing frames 15. The ink delivery roller 33 is preferably made up of several longitudinally spaced sections separated bygrooves or gaps 33 and secured to a common shaft 36, the ends of which are journaled in the above noted bearing boxes 34. Running in engagement with the said roller 33 is a distributing roller 37, the shaft of which, as shown, is detachably mounted in bifurcated arms 38 of the bearing frames 15. At their free outer ends, the

bearing frames 15 are secured to a troughlike ink font 39 having a spring metal bot? .tom plate 40, the lower edge of which is in constant and close engagement with an ink take-up roller 41, the shaft of which projects at one end and is providedloutside of the ink font with a ratchet wheel 42. This ratchet wheel is engaged by a driving dog 43 carried by the free outer end of a cam lever 44, that is pivotally mounted on the shaft of said roller 41 adjacent to the said ratchet wheel 42. Once at each rotation of the auxiliary printing cylinder, a cam projection, preferably in the form of a roller 45, carried by one of the heads 21, engages 'the depending curved end of said cam lever 44, forces the same upward and causes the dog 43 to impart a step of rotary movement to. the ratchet wheel 42 and to the take-up roller 41. The engagement of the free lower edge of the spring bottom-plate 40 with the roller 41 is maintained and properly regulated'by a multiplicity of set screws 46 applied in the bottom portion of the font 39. The lever 44 is retracted or returned to normal position by its own weight. An ink transfer roller 48 is loosely journaled in an upwardly projecting arm 49 of a rock shaft 50, that is loosely journaled in. the bearing frames 15, and provided with a depending arm 51 preferably equipped at its free end with a roller 52. A coiled spring 53, shown as attached to the font 39 and tea projection on the hub of the arm 51 yieldingly holds the roller 48 engaged with the roller 37. One of the cylinder heads 21 carries a cam plate 54 that is adjustably secured thereto, as shown, by a screw 55 engaged with said head and working through the segmental slot 56 of said cam plate. On'ce at each rotation of the auxiliary printing izs cylinder, this cam plate 54 engages the roller '52 and forces the ink transfer roller 48 from engagement with the roller 37 into engaglment with t e roller 41, and inthis way t e ink is taken up from the font 39 and delivnoted, are of different length. This permits the same to be put together-on the shaft 36 indifferent wa s so that each roller section will cover di erent zones of the print:

ing surface represented by the set type Y and Y Bymeans of movable partition plates 57, the ink font may be divided into sections corresponding in number and in length and location to the sections of the delivery roller 33. These partition plates 56 should be cut on their edges to closely -fit the inclined bottom plates 40 and the adjacent surface of the roller 41. In practice, we have found that they may be held in position by glue or even by putty. Ink of different color may be placed in the several compartments of the font and the several colors of ink will, by the several intermediate rollers 37 and 48, be delivered to the respective sections of the roller 33, In this ,way, the-auxiliar'y printin device may be made to simultaneously prin in several different colors, the differentcolors being distributed over the zones or areas which are variable by adjustment of the partitions 57 and of the sections of the roller 33. a

What we claim is:

1. The combination with a printing press having printing devices including a paper,

delivery cylinder, of an auxiliary printing cylinder cooperating with said paper delivery cylinder, type-holding means-on said auxiliary cylinder adjustab e lengthwise of the latter, and inking mechanism to supply inks of different colors to different sections or zones of said auxiliary cylinder, said mechanism comprising an ink-font divided into adjustable compartments, and an ink- 'ingroller divided into. adjustable said ink-font compartments beiug ad ustahle independent of the adjustment of said inking roller segments sothat the length of the compartments of theink-font can be made to substantially 'corres nd to the length of the se cuts of the roller.

2. he combination wi a. press having printing devices including a paper delivery cylinder of an auxilia 1 printing cylinder cooperating with ,said d eli very 'cylinder, type holding means on said auxiliary cylinder and adjustable lengthwise thereof, and an automatic inking device'cooperative with said auxiliarycylinder and comprising a sectional inking roller tocontact therewith and a sectional ink-fontf toj deliver inks of different colors to the respective sections of said inking roller, the sections .of said inkfont and inking roller being adjustable .independent of each other to vary the widths of the printing zones. 7

3. The combination with-a printing ress having a paper delivery cylinder, 0 ad justable shaft bearings in the vicinity of the ends ofsaid cylinder, a shaft journaled in said bearings, an auxiliary printing cylinder carried by said shaft for cooperation with devices on the periphery of saidauxiliary printing cylinder, bearing frames pivotally mounted on said shaft and extendmg bot above and below the 'same, anchoring devices applied to the lower ends of said bearin frames, and an ink font and ink delivery 75, said paper delivery cylinder, type-holding ml ers mounted on the upper. portions, of

said bearing frames fordelivering ink to ty e carried by said auxiliary printing c lin er, the said inkin rollers being driven y said auxiliary cylin er. 1
